As I need this to be a quick post today, below is an extract from Wikepedia

The Red Rock-Secret Mountain Wilderness is a 47,194-acre (191 km2) wilderness area located within the Coconino National Forest in the State of Arizona.

The Wilderness is predominantly wind and water sculpted pinnacles, windows, arches, and slot canyons, and the red-rock cliffs of the Mogollon Rim that mark the edge of the Colorado Plateau. Bordered on the east by Sycamore Canyon Wilderness, the high mesas of Secret Mountain and Wilson Mountain jut out into the lower country and canyons as deep as 1,500 feet (457 m) drain into Oak Creek and the Verde River.

Prehistoric rock art and abandoned cliff dwellings can be found in the Wilderness.
